(Cl. 20656) This inventionrelates to improvements in the feeding of strip material selectedlengths of which are to be severed and more particularly to the feedingof stamps, such as trading stamps and the like, by providing a novelcombination of aligned perforations of different dimension and spacingso they will accommodate the pins or cogs formed on a feeding wheel ordrum, whereby the stamps may be utilized in different commercial stampfeeding machines where the spacing of the cogs or pins on the feedingdrums are of different relative spacing.

One of the objects of the invention is to provide a strip of materialsuch as a strip or sheet of stamps with an array of aligned perforationsso positioned that they will function to define a weakened line tofacilitate severing of selected lengths of the strip such as individualstamps or groups of stamps, and that they will furthermore facilitatethe feed of the strip through any one of several different dispensers.

Another object of the invention is to arrange aligned feedingperforations of different dimension and spacing in parallel rows in astrip of material such as a sheet of stamps with similar perforationsand longitudinally aligned to accommodate feeding drums utilized invarious stamp dispensing machines having a similarly transversely and/or longitudinally arranged array of feeding pins or cogs.

A further object of the invention is to provide a strip of material suchas stamps with a transversely aligned array of perforations of bothfirst and second predetermined dimensions, or a series of paralleltransversely arranged arrays of such perforations in which theperforations of the first predetermined dimension are transversely andlongitudinally aligned and are interposed between perforations of thesecond predetermined dimension similarly transversely and longitudinallyaligned with each other and wherein such transverse rows of perforationsalso form weakened severance lines to thus provide for feeding of thestrip of material by any one of a plurality of dispensers as well as theproper separation of selected portions of the strip of material.

A further object of the invention is to provide stamps in single strip,multiple strip or sheet form, all of which are provided with a patternof spaced parallel rows of perforations of predetermined sizes andspacing, with some of said perforations being of a first predetermineddiameter and some of said perforations being of a second predetermineddiameter such that the stamps can be fed from dispensing machines havingfeed pins or cogs which are arranged in a plurality of differentpatterns such as is found in conventional stamp dispensing structuresnow available.

Another object of the invention is to provide a strip of material suchas stamps with an array of spaced parallel rows of alternately disposedlarge and small perforations of various configurations.

These and other objects of the invention will more clearly hereinafterappear by reference to the accompanying drawings forming a part of theinstant specification and wherein like characters of reference designatecorresponding parts throughout the several views, in which:

FIG. 1 is a plane view of a portion of a strip of stamps, one stampwide, embodying the present invention;

FIG. 2 is a similar view of a strip of stamps two stamps wide;

FIG. 3 is a view of a strip of stamps with each stamp 3,333,688 PatentedAug. 1, 1967 having a greater transverse dimension than the stamps shownin FIGS. 1 and 2 and embodying the present invention;

FIG. 4 is a fragmentary plan view of a section of a sheet of stamps;

FIG. 5 is a diagrammatic view showing the perforations enlarged with anillustration of the relative arrangement and sizes of the perforations;

FIG. 6 is a fragmentary plan view of a sheet of stamps embodying theinvention;

FIG. 7 is a view similar to FIG. 6 in which perforations are of diamondshape;

FIG. 8 is a top fragmentary view of a feed roller with its associatedcogs or pins;

FIG. 9 is a view similar to FIG. or pin;

FIG. 10 is another view showing the roller provided with a pair of largecogs for engaging the larger spaced perforations;

FIG. 11 is a view similar to FIG. 8 in which the feed roller is providedwith a pair of spaced large cogs or pins and a pair of smaller cogs orpins for driving a sheet having similarly arranged perforations;

FIG. 12 is a perspective view of a feed roller associated with a stripof stamps, the feed roller having three large cogs for engaging threelarge spaced perforations of the p;

FIG. 13 is a modification in which a strip is provided with a singlelarge perforation and a multiplicity of smaller perforations at eachside; and

FIG. 14 is a diagrammatic view showing the relative association ofperforations in stamp assemblies illustrating a modified arrangement ofcogs on the feeding drum and the relative spacing.

In FIG. 1 a section of a stamp strip E, one stamp wide, is shown inwhich a longitudinally extending (in the direction of arrow Z FIG. 1)and aligned row of large perforations 1, having a predetermined diametersuch as .093", have their centers equally spaced longitudinally (in thedirection of arrow Z FIG. 1) of the strip to receive similarly spacedcogs or pins on a drive wheel or drum in a dispensing machine of anysuitable type. The large perforations 1 are centrally spacedtransversely of stamp strip E (in the direction of arrow X-FIG. 1) andit will be noted in FIG. 1 that the width of the stamp strip shown issuch that laterally spaced large perforations 1a of the same diameter asperforations 1 are intersected and preferably bisected by thelongitudinal sides of strip E.

Small perforations 2 each 0.040" in diameter are longitudinally andtransversely aligned with each other for engaging cogs or pinsappropriately arranged on a drive wheel or drum of a dispenser ashereinbefore mentioned. However, small perforations 2 are more closelypositioned with respect to the large center perforation 1 than to thelarge laterally positioned perforations 1a. It will be seen from aninspection of FIGS. 5 and 14 that the centers 15 of small perforations 2are spaced a distance 0.140" from the center 19 of large perforation 1and are spaced -a distance of 0.149" respectively from the centers 21 oflarge perforations 1a while the centers 21 of large perforations 1a arespaced a distance of 0.289" respectively from the center of largeperforation 1 for an overall center to center distance between thecenters 21 of large perforations 1a of 0.578". There it will be seenfrom FIG. 5 the a+b=a'+b'.

This same relative perforation size for large perforations 1 and 1a andsmall perforations 2, and spacing between large perforations 1 and 1aand small perforations 2 is utilized carried for all of the stampassembly forms, i.e. single strip, multiple strip or sheet, andcorresponds to the size and spacing of the large cogs 23 (FIG. 14)

8 with a single cog and the small cogs 25 of a dispenser feeding drum27.

By the arrangement shown, dispenser feeding drums having only small pinsor cogs (33FIG. 8), only large pins or cogs (35FIG. 9, 42-FIG. 10 or53-FIG. 12), or both large and small pins or cogs (47 -FIGS. 11 and 14)may be utilized, to perform the feeding function of a stamp strip ofsingle or multiple form, or of a stamp from a dispenser. As a result ofthis concept, it is unnecessary to provide a special arrangement ofperforations for different customers having different types of stampdispensing machines as the disclosed novel arrangement of perforationsaccommodates a multiplicty of drive pin or drive cog arrangements. Itwill be understood that not only does the spacing of feed pins or cogson feeding drums in dispensing machines vary in many instances, but alsothat the relative size of the driving pins or cogs may vary, and it willbe obvious to one skilled in the art that it is unnecessary to have thepins of the same identical diameter as the perforations in which theyengage, as the feeding operation results from the engagement of a pin orcog with the wall defining the perforationj a a It will be furtherobvious that the sizes and spacings of the perforations 1, 1a and2 andof the cogs 23 and 25 is subject not only'to normal tolerances but mayalso be varied within the scope of the'disclosed concept.

It should of course be recognized that the perforations 1a, 2, 1, 2, 1aalso define a transversely disposed weakened line 29 (FIG. 1) tofacilitate severance of the stamps one from the other.

In FIG; 2 there is illustrated a strip of stamps F two stamps wideseparated by longitudinally arranged (in the direction of arrow Z)perforations 3 and provided with a transverse (in the direction of arrowX) row of large perforations 1b and interposed small perforations 2a;with laterally spaced large perforations 1c intersected and preferablybisected by the longitudinal sides of strip F. Perforations 1b and 1cand perforations 2a are espectively disposed for accommodating cogs orpins on a suitably proportioned dispenser feeding drum. In theembodiment of FIG. 2 the strip F is adapted to he travelled in thedirection of arrow Z. Dual strip of stamps F of FIG. 2 can belongitudinally separated by the provision of perforations 3 or can betransversely severed along the weakened line 29a formed by perforations10, 1b and 2a, it being noted that these perforations are sufficientlyclose to provide a convenient severance point for delivery of stamps ofa predetermined amount. It is to be understood that the relative size ofand spacing between large perforations 1b and 1c and small perforations2a are the same as those previously described with respect to FIGS. 1,5, and 14.

In FIG. 3 there is shown a strip ofstamps G two stamps wide havinglongitudinally extending :(in the direction of arrow Z) severanceperforations 3a each, the strip being of a width greater than the widthof the individual stamps of FIGS. 1 and 2. Because of this increasedwidth, each individual stamp includes a number of transversely disposed(in the direction of arrow X) large perforations 1d and 1e and smallperforations 2b and 2c in excess of the number of perforations for stripF of FIG. 2 with perforations 20 being intersected and preferablybisected by the longitudinal edges of strip G. As shown, each individualstamp strip of the dual strip G includes two complete large perforations1d and two complete small perforations 2b. In this embodiment thelongitudinal severance perforations 3a intercept large intermediateperforations 1e in each transverse array of perforations By the embodi-'ments of FIGS. 1, 2 and 3 it will be obvious that the same concept andarrangement of perforations can be utilized regardless of whether asingle strip of stamps is being dispensed or whether a strip two or morestamps wide is; being dispensed. Further it will be obvious that thesame inventive concept. with reference to the perfora-i tions can beembodied in stamps regardless of their width, it merely being necessaryto have arrays of smaller and larger perforations to accommodate feedwheels or feed drums with corresponding registering pins or cogs.

Further in connection with FIGS. 1, 2 and 3, it will be obvious that thesame principle may be utilized on a strip of stamps including so-calledhalf strips which may be arranged at either margin of the strip andrepresent a relative value with respect to the whole stamp. Forinstance, the strip shown in FIGS. 2 and 3 may instead of being twowhole strips of stamps comprehend an additional stamp, i.e. be two andone-half stamps in width and the same thought can be expanded to providefour and one-half stamps or other proportionate arrangements 7 as it iscontemplated that the embodiment of FIG. 4 rep-' resents a relativelylarge sheet of stamps, it will be obvious that this sheet may be fedeither longitudinallylin the direction of arrow Z) or transverselythrough a'stamp dispensing apparatus; it only being necessary that thepins or cogs register with certain predetermined spaced feedperforations in accordance with the movement of the sheet through thedispensing apparatus, as indicated by the arrow Z at the right side ofFIG. 4.

.The perforations functioning for the feeding of the sheet of FIG. 4 canalso operate as severance perforations to facilitate removal of atransverse strip of stamps or individual groups of stamps by includinglongitudinally extending severance perforations 3b. I 7 i In FIG. 6there is illustrated a section of a sheet of stamps in which thetransverse (in the direction of arrow X) perforations are arranged andare of a size corresponding to the size and arrangement of theembodiments of FIGS. 1, 2 and 4 with the spacing corresponding to thediagrammatic view of FIGS. 5 and 14. In this figure large perforations1g in the transversely spaced arrays of perforations have interposedtherebetween small perforations 2e. The arrangement of perforations issuch that a large perforation 1h is located centrally at the transversecenter of each stamp with longitudinal (in the direction of arrow Z) twolaterally spaced large perforations being intersected by the severanceperforations 30. In this connection it will be noted that strips ofstamps can readily be severed from a sheet, such as shown in FIG. 6, andonce obviously accommodate pins or cogs similarly shaped, or 7 larger orsmaller pins of annular form in cross section. The perforations 3d mayeither be circular as shown or of diamond or any other suitable shape.

In FIGS. 8, 9, 10 and 11 there are illustrated in frag mentary viewportions of feed drums or spools with associated strips or sheets ofstamps in which are illustrated modified arrays of feed pins for normallongitudinal feeding of the stamps. While the disclosures of FIGS. 8through 11 are illustrative of modified forms of pin arrays for feedingstrips or sheets, it will be obvious to one skilled in the art that.other arrangements of feed pins on the feed drums can be readilyprovided, aslong as these the alternate one direction or the otherdirection, in

in the strips or sheets of stamps to provide the essential drive by thefeed drum of the strip or sheet. It is to be understood that FIGS. 8through 11 are for the purpose of illustration and the elements, i.e.,'the drum and the sheet, are relatively enlarged.

As is known in the art, the driving medium, i.e., the pin or cog, orpins or cogs, provided on the feed drum, will be of a size and number toproperly and accurately advance its associated strip or sheet and inthis connection other factors may be involved such as the nature of thestrip or sheet being fed, including the width of the sheet, its relativestiffness, the speed of the feeding, the nature of the coating and otherfactors may necessarily be considered.

In FIG. 8 a section of a feed drum 33 is illustrated having four smallpins 34, all of the same dimension for engaging the walls of thetransverse perforations of a strip or sheet similarly arranged and ofapproximately the same size. Such an arrangement of feed pins on a feedroller could readily be associated with the basic arrays of perforationsshown. It should be understood that a small pin 23 will pass into andthen out of a large perforation, such as perforation 1 of FIG. 1,without engaging the sides thereof and that the feed will be imported tothe strip by those small pins 34 which engage the walls of perforations.

In FIG. 9 a feed drum 35 is shown with a single large pin 36 forengaging large perforations 1m in a strip or sheet, it being understoodthat the strip or sheet section 38 is fragmentary and that in the eventfeed drum 35 is used in connection with a sheet, additional large pinsmight be appropriately spaced along feed drum 35 to provide thenecessary feeding of the sheet.

In FIG. a strip or sheet 39 is shown to include large perforations 1nand small perforations 2g spaced between the large perforations 1n. Inthis embodiment a feed drum 42 is shown provided with a pair of spacedlarge pins or cogs 43 there being no pins or cogs for engagement withsmall perforations 2g of strip or sheet 39.

i In FIG. 11 a strip or sheet 44 is shown provided with spaced largeperforations 1p and intermediate small perforations 2h. The strip orsheet 44 is shown driven by a drum 47 provided with the large pins orcogs 48 appropriately spaced for engaging the large perforations 1p inthe strip or sheet 44. Smaller pins 49 are shown on drum 47 positionedbetween large pins or cogs 48 for engaging the small spaced perforations2h.

In FIG. 12 a strip of stamps 50 is shown having an array of large andsmall transverse perforations 1r and 2k, respectively, alternatelyarranged in a manner similar to that shown in FIG. 2. In this figure afeed drum 53 is shown provided with three large pins or cogs 54 suitablyspaced for engaging the three large transversely arranged perforations1r.

In FIG. 13 a strip of stamps 55 is illustrated in which the transverseseverance point includes a central large perforation 1s and amultiplicity of smaller perforations 2m, small perforations 2m beingrelatively closely associated to facilitate severance with one of eachgroup of smaller perforations 2m spaced with respect to largeperforations Is in accordance with the showings of FIGS. 5 and 14. In astamp strip such as shown in FIG. 13, a feed drum may be utilized havinga series of spaced small cogs to engage certain of the small transverseperforations 2m of the strip or a feed drum could be utilized having asingle feed pin or cog for engaging the large central perforations 1s,such a feed drum being illustrated in FIG. 9.

It will be noted by reference ing between the centers of the rows oftransverse perforations is .875" and this dimension will be the basicspacing pins on feed wheels or rolls for feeding the various strips andsheets in the normal manner or in a longitudinal direction.

It is not the intent of applicant to limit his concept to FIG. 4 thatthe spacexcept to the extent of providin various spacings of feedperforations in a strip, sheet or roll of stamps which are soconstructed, arranged and positioned that such a sheet, strip or rollwill be adaptable for use in the numerous conventional arrangements ofcogs and pins provided on conventional stamp dispensing machines. Inother words, by the present concept it is not necessary to provide aspecific array of feed perforations for use in a specific machine, butrather it is contemplated that there shall be an array of perforationsmodified as to size and spacing provided in a strip or sheet of stampsso that it can be fed by any standard stamp feeding or vendingequipment.

While the present illustrations are directed primarily to large andsmall feed perforations alternately arranged, it is possible that morethan a single small feed perforation can be arranged between each of thespaced larger feed perforations. Also in this connection, while it iscontemplated that the larger perforations be regularly spaced in alongitudinally extending line, the smaller perforations may beappropriately arranged both as to number and as to spacing.

As stated above, the purpose of the instant concept is to permit the useof a strip, sheet or roll of stamps in a plurality of types of machineshaving a different array of feed cogs or pins, thereby preventing theexpense of duplication in the manufacture of stamps for general sale tosources where the stamp feeding or vending machine may have modifiedarrays of feed cogs or pins.
